@ It's Mrs. Draper To YouI don't think the PRs of Harry Winston care about trolling the GG fandom. Their only interest is advertising their product, which means they would never associate it with something that represents a failure. An engagement ring (the Classic Winston Ring in this case) is not supposed to be used for closure. I'm pretty confident that they made sure they knew about the finale outcome before having Ed and Leighton attend the event.

@ lulu You explained the difference between the two situations perfectly. In fact Dan did what he did also because he knew he had nothing to lose, Blair's doubts were about Chuck and Louis. Would have Dan done the same thing if he thought he stood a chance? I don't think so.When Chuck let Blair go she was willing to break off the engagement with Louis to be with him. He had everything to lose.
